HAY-SLING.

Specification of Letters atent.

Application filed January 24, 1911.

Patented July 9, 1912. serial No. 604,418.

To a LU/tom t may concern:

Be it known that I, EDWARD THOMPSON, a citizen of the United States, residing at York, in the county of Benson and State of North Dakota, have invented a new and useful Hay-Sling, of which the following is a specification.

This invention has relation to hay slings and locks for the sections thereof, and consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide a sling of the character indicated which shall be of simple structure and will effectually support a load, and which shall be provided with a lock of novel construction and peculiarly located upon one of the sections of the sling in such manner that the possibility of the lock becoming prematurely or unintentionally opened is reduced to a minimum; but if this should by any means happen, the sections of thesling may be readily withdrawn from beneath the bundle or load of hay.

In the accompanying drawings,-Figur 1 is a plan view of the sling. Fig. 2 is an enlarged detail plan view of the lock thereof. Fig. 3 is a longitudinal sectional View of the lock, taken on the line 3-3, Fig. 2. Fig. 4 is a transverse sectional view of the lock, taken on the line 44 of Fig. 2.

As illustrated in the accompanying drawings, the hay sling consists of sections A and B. The Section A is made up of a single. bar 1 having a cable 2 trained through the ends thereof and provided at one side of the bar 1 with an eye 3 to which hoisting cables may be attached, and at the other side of the bar 1 with an eye 4 which forms a portion of the locking device for the two sections A and B. The section B consists of a bar 5 through the ends of which is trained a cable 6 and at one side of the bar 5 an eye 7 is attached to the cable 6, and to the eye the hoisting cable may be connected. The shank 8 is attached to the cable 6 at the opposite side the bar 5 and a bar 9 is rigidly mounted upon the shank 8, the bar 9 being equal in length to the bars 1 and 5 and constituting an intermediate hay support.

A bill 10 is pivotally mounted at a point intermediate of its ends upon the upper side of the shank 8 and at one end is adapted to bear against the upper Surface of the shank,

as shown in Fig. 3. The shank 8 is provided upon its upper side, and in the vicinity of the bar 9, with parallel walls 11 adjacent to one of which is formed or located a housing 12. A bolt 13 is located in the housing 12 and is provided at its free end portion with an Venlarged head 14 which normally lies transversely across the space between the walls 11 as shown in Fig. 4.

A coiled spring 15 is located within the housing 12 and bears at one end against. the end of the housing and at its other end against the end of the head 14 and is under tension with a tendency to hold the head 14 across the space between the walls 11. That end of the bill 10 which does not encounter the upper surface of the shank 18 lies in the space between the walls 11, and when the end of the bill does come in contact with the Surface and the shank 8 is in engagement with the same, its opposite end is above the upper side of the enlarged head14 of the bolt 13. Thus when one end of the bill 10 is against the upper surface of the shank 8, the head 14 lies under the other end of said bill and holds the bill against movement upon its pivotal connection with the shank 8. Therefore when the outer end of the bill 10 is projected through the eye 4, the latter is retained with relation to the said bill and shank 8. A guide 16 is mounted upon the sides of the bar 9 beyond one end of the housing 12 and a trip cord 17 is connected at one end with the bolt 13 and passes through the guide 16; thence passes around a swivel pulley 18 located at the end of the bar 9, and the disconnected end of the trip rope being free to hang down. By Such an arrangement it will be seen that a sling is provided which is of simple structure and in which one of the members of the locking device for the two sections is iXedly mounted upon one of the bars and the trip rope is guided to the end of the bar, and at the end may hang free, and thus always be within convenient reach of one standing under the load, and further is not liable to become entangled, whereby the operation of the lock will not be interrupted.

When it is desired that the members of the locking device shall be operated, the operator pulls the trip rope 17, or an automatic tripping device may be provided, and thus the enlarged head 14 of the bolt 13 is withdrawn from under the inner endl of the bin 1o and the Outer mi of the bin is thereby rendered free `to swing in .an .up- Ward direction away from the shank 8.

any cause the members of the locking device should become disconnected prema` til-rely, .and the 'load all .upon -the sections of the sling, fthe parts yare so assembled I@that the .sections maybe #readily withdrawn from under the load without necessitating the removfal fof #the :load from the sling sections by hand. V

Having described the inyentiom'what claim as ,new and desire to `secure by `Letters Patent is A sling comprising ,twovsections, ,one of which consists of a vbar having a cable trained about its ends and an eye attached shank attached to the -last mentioned cable,

:and an intermediate bar equal in length to the other bars and rigidly mounted upon Vthe shank and disconnected from the cables and constituting an intermediate hay support, a bill pi-Votally mounted upon the shank, and locking means carried by the shank and adapted to hold one .end .of the bill 1in contact with the surface joit the shank and projecting through :the eye, .and means for releasing the locking device.

:In testimony .that '-I claim the foregoing as vmy own, I have zhereto ,affixed my signature in the presence of two witnesses.
